Just installed an AVO turbo, STi top mount and Walbro Fuel Pump on an MY03 WRX and put it on the dyno for a Vi-pec install and tune.




Vipec ECU was installed and tuned as well. Stock power was at 191hp with the Power Torque curves very wavey and all over the place. We installed the Vi-pec and achieved 264hp at 1.15bar and smoothed out the power and torque curves.

Below is the comparison graph of before and after Power and Torque:
